Heat Transfer Performance Of Double Tube Hairpin Heat Exchager By Using Cfd Analysis With Mgo Nano Fluidat Different Volume Fractions

Heat exchanger is a device used to transfer heat between one or more fluids. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. In this thesis, MgO nano fluid is mixed with base fluid water is analyzed for their performance in the hair pin heat exchanger. The nano fluid MgO is mixed with water at different volume fractions (0.000625, 0.00125, 0.0025, 0.005 and 0.01). Theoretical calculations are done determine the properties for nano fluids and those properties are used as inputs for analysis. 3D model of the hair pin heat exchanger is done in CREO parametric software. CFD analysis is done on the hair pin heat exchanger with MgO nano fluid at different volume fractions and thermal analysis is done in ANSYS for two materials Aluminum7085 and Copper.
